Low-power audio/video compression

Hikvision Digital Technology has launched its DS-42xxHCI/HFVI series audio/video compression card. It adopts a high-performance video processing chip, standard H.264 video codec and realtime audio/video capturing and encoding. The series models include DS-4216HFVI, DS-4208HFVI, and DS-4216HCI.

Some of the main requirements for compression cards today are stability, flexibility, and the ease of development and customisation. By adopting a high-performance processing chip that can support up to 8 channel 4CIF realtime encoding, the DS-42xxHCI/HFVI series audio/video compression card requires fewer chips on the board resulting in low power consumption and higher stability. A full SDK and demo source code is also available, which provides a platform for customisation. In addition, the on-board video/audio input pins allow users to build a PC-based DVR system with their preferred physical video/audio input interfaces; its termination jumper design on each 75 Ω matching resistor also enables the video loop out function as an option.

Hikvision’s DS-42xxHCI/HFVI series delivers up to 16 channel 4CIF (main stream) realtime encoding and 16 channel CIF (sub stream) encoding on dual stream mode, which enables the product to record in high quality and full frame rate, and at the same time to cover the requirements on narrow band transmission and cellphone surveillance applications. The product also features 25 fps (PAL)/30 fps (NTSC) and supports variable bit rates and frame rates, motion detection, OSD auto switch, LOGO and MASK overlay.

The product is available in three models: The DS-4216HFVI supports 16 channel 4CIF realtime recording, and up to 16 channel 4CIF (main stream) and 16 channel CIF (sub stream) encoding in dual stream mode; the DS-4208HFVI supports 8 channel 4CIF realtime recording, and up to 8 channel 4CIF (main stream) and 8 channel CIF (sub stream) encoding in dual stream mode; the DS-4216HCI supports 16 channel CIF realtime encoding, 16 channel 4CIF or 2CIF encoding with 5 fps, and up to 16 channel CIF (main stream) and 16 channel CIF (sub stream) encoding in dual stream mode.
